I have one and it works very well. I have it mounted above the
normal attitude indicator, so the airspeed indicator and altimeter are
within my field of view, unlike the turn coordinator. If you are
turning to the right, the LEDs on the right light up, increasing with
the turn rate. The Tango 2 that I fly has a stick, so the logic I use
is move the stick to the left to move the lights back to the middle,
and vice-versa. For pitch control, vertical LEDs do the same thing. I
think that with some practice it is a great little backup instrument.
